captthomason,

This might become a feature of GPSed in the future, but not the nearest one. You see, GPSed mobile application browses it's own map and shows you your track and location on this map. It is not Google maps, so it is difficult to locate your friends relatively to you from the BlackBerry.
Web service GPSed.com on the PC shows Google maps in any scale. This way besides seeing your tracks, you can locate your friends on the map.

Best regards,
Irene
